5 times what number will be negative 7?

Answers

Answer:

-1.4

Step-by-step explanation:

5*X = - 7

5x= - 7

X= - 7/5

X= - 1.4

5x = -7
Divide both sides by 5.
X = -7/5 or -1.4

Which inequality models this situation? The time between two trains must be greater than 37 minutes.

A.
t < 37

B.
37 > t

C.
37 – t = 0

D.
t > 37

Answers

The inequality t > 37 models the equation correctly, in which it is stated that the time between two trains must be more than 37 minutes. Here, t represents the time between the two trains.

Given the graph below, find GH.-
Is this asking to find the coordinates, or to find the distance?

Answers

Answer:

$GH = 6.3$ (nearest tenth)

Step-by-step explanation:

Given:

G(-2, -3)

H(0, 3)

Required:

Distance between point G and H = GH

Solution:

Distance between G(-2, -3) and H(0, 3):

$GH = √((x_2 - x_1)^2 + (y_2 - y_1)^2)$

Let,

$G(-2, -3) = (x_1, y_1)$

$H(0, 3) = (x_2, y_2)$

$GH = √((0 - (-2))^2 + (3 - (-3))^2)$

$GH = √((2)^2 + (6)^2)$

$GH = √(4 + 36) = √(40)$

$GH = 6.3$ (nearest tenth)

5x+y=2 2x3y=62
whatn is x and y

Answers

5x + y = 2 ⇒ 10x + 5y = 4
2x + 3y = 62 ⇒ 10x + 15y = 310
         -10y = -306
      -10 -10
   y = -30.6
      5x - 30.6 = 2
   +30.6 +30.6
      5x = 32.6
   5 5
      x = 6.52
   (x, y) = (6.52, -30.6)

ok sure!
first we have to find y

so...
lets start with the first one:

5x+y=2 (we cannot have two variables together so:
5x+y=2
-y =-y so.. now we have 5x= 2-y (but we must get y positive and by itself!)
-2 = -2
so: now you have
5x-2=-y but need a positive variable so multiply each side by a (-1)
(-1) 5x-2=-y (-1) So..
-5x +2 =y so now we know Y!
therefore whenever you see why in the next problem insert in its place: -5x +2

I hope it helps!! :)
